When you've got a big night out planned and you want to look your best, sneak in a sweat session a couple of hours before your event. Ideally, you should mix cardio with weight-bearing exercises, concentrating on doing reps that engage your major muscle groups (particularly if you're short on time), as this technique will make your muscles look ultra-toned for several hours. Plus, exercising will boost your confidence and give your skin a healthy glow. Just make sure to shower afterward.
